PISÉ walls are currently being installed in several Northern California counties. Easton continues his research and development into quick-lock forming systems, versatile mix designs, soil amendments, and improved delivery equipment. The intention of the company is to soon make the PISÉ system available to a wider market, but because the process is much more complex than traditional rammed earth, requires sophisticated equipment, and meticulous control over mix designs, the technology is intentionally being introduced slowly. Only after a thorough training program can a subcontractor be considered qualified to shoot PISÉ walls.
